Use Case Estimation

Project estimation is the task of working out how much time and effort is required to build and deploy a solution.

The Use Case metrics facility in Enterprise Architect provides a starting point for estimating project effort; using this facility you can get a rough measure of the complexity of a system and some indication of the effort required to implement the model. Like all estimation techniques, Use Case metrics requires some experience with previous projects to 'calibrate' the process.

There is additional information available on Use Case metrics on the Sparx Systems website.

Calibrating

These values must be carefully calibrated in order to gain the best possible estimates:

Technical Complexity Factors, which are values that attempt to quantify the difficulty and complexity of the work in hand

Environment Complexity Factors, which are values that attempt to quantify non-technical complexities such as team experience and knowledge
